Product Description
1.Designed and manufactured as per API.
2.Non Weld Bow centralizers are used to position the casing in the
center of the wellbore in vertical, deviated as well as horizontal
wells.
3.The Non Weld Bow Centralizers combine the highest Non Weld
Centralizer restoring force with the lowest starting force.
4.High quality Bows made of special alloy steel with uniform
hardness provide optimum performance.
5.The bows with extended profile prevent them from hitting against
casing collars.
6.Hinge locking pins are of high strength steel for maximum
structural robustness .
7.Bows are then Flattened several times on a special machine to get
permanent setting.
8.Centralizers undergo a special process of rust prevention before
powder coating.
9.The Non Weld Bow spring centralizers are available in sizes
4-1/2" to 20".

Bow-spring centralizer
1.These Centralizers are designed for High Restoring Force and Low
Starting Force for centralizing the casing pipe in a
Vertical,Horizontal and Deviated well
2.Premium quality Bows are made of special alloy steel and hot
formed in totally controlled heat treatment plant
3.Spec and performance index of bow spring casing centralizer meet
API Spec 10D. The woven centralizer is connected by pin when in
use, the unfolded centralizer can be stacked flatly for convenient
storage and transportation.
Rigid roller centralizer
Rigid casing centralizer is used in deviated wells and horizontal
wells. There are several blades on the rigid roller
centralizer that can keep casing from contacting the well bore wall
